Brain’s Waste Removal System More Active During Sleep

Even our brains need to take out the trash.

Researchers from the University or Rochester Medical Center found that a waste-flushing system in the brain, called the glymphatic system, is most active when we sleep — nearly 10 times more so than during periods of wakefulness, in fact.

Plus, during sleep, brain cells shrink in size by 60 percent to better allow for the removal of waste from the brain.

“This study shows that the brain has different functional states when asleep and when awake,” study researcher Maiken Nedergaard, M.D., D.M.Sc., the co-director of the university’s Center for Translational Neuromedicine, said in a statement. “In fact, the restorative nature of sleep appears to be the result of the active clearance of the by-products of neural activity that accumulate during wakefulness.”

The findings, which are published in the journal Science, are based on brain imaging…

Chakras DeMystified – Part 2 – Prana: The Universal Life Force

If ‘steadfast awareness or super subtle pure conscious’ is the quintessence that permeates everything in the observable universe and beyond, then Prana is its universal principle of energy or force. It is the sum total of all energy that is manifest in the universe, all the forces in nature and powers which are hidden in men and which lie everywhere around us.

Swami Sivananda Saraswati says:

Prana is force, magnetism and electricity. Radio waves travel through prana. That which moves the steam engine of a train and a steamer, which causes the motion of breath in lungs, that which is the very life of this breath itself, is prana. It is prana that pumps the blood from the heart into the arteries or blood vessels. Through prana digestion, excretion and secretion take place. Prana digests the food, turns it into chyle and blood, and sends it into the brain and mind. The mind is then able to think and enquire into the nature of Brahman.

Prana is the link between the astral and physical body. When the slender thread-link of prana is cut, the astral body separates from the physical body. Death takes place. The prana that was working in the physical body is withdrawn into the astral body.

How is Prana related to the Chakras?

In the pranic body, prana flows through nadis, energy channels, and is stored in chakras, energy vortices. According to some researchers, the electromagnetic energy in prana gives rise to radiation in which the waves of electric energy and magnetic energy are at ninety degrees to each other, resulting in what looks like a spiral. Indeed, the spiral radiation structure around chakras has been seen, described and drawn by sages and savants from all parts of the world at different times.
At the pranic level, in their initial stages the practices of pranayama clear up the nadis, energy pathways in the body. The scriptures say there are over 72,000 nadis or pathways of prana in the pranic body and six main chakras. However, in the average individual, many of these pathways are blocked and the chakras release energy only partially. In other words, we do not utilize our full potential in terms of energy, mind and consciousness. The negative conditions we experience, whether physical or mental, are the cause as well as the consequence of the blockages. The state of our nadis and chakras are defined by our samskaras, conditionings carried in seed form, as well as purushartha, self-effort and anugraha, grace. When these pathways of energy are gradually freed so that prana moves through them smoothly.


Nāda: The MicroCosmic and MacroCosmic Rhythm

Most of us can remember a fundamental concept taught to us in school when we learned of Molecular Motion, States of Matter and Gas Laws:

“All molecules are in constant motion. Molecules of a liquid have more freedom of movement than those in a solid. Molecules in a gas have the greatest degree of motion.”

We now know that even atoms and sub atomic particles are in constant motion. Everything from within the microcosm to the macrocosm is in perpetual motion. Incidentally, this concept has also been integral to the authoritative religious texts in Hinduism. Some intuitive findings of the ancient seers or Rishis, of India,  are based on the premise that the entire cosmos and all that exists in the cosmos, including human beings, consists of sound vibrations, called nāda. This concept holds that it is the sound energy in motion rather than of matter and particles which form the building blocks of the cosmos.

Dr. Robert E Svoboda maintains, in his article THE SOUNDLESS SUSURRATION OF THE KINDLY HEART ” Viewed from the perspective of creation, nada is “that which expresses,” the sound current from which manifestation occurs. From the perspective of dissolution, however, nada is the resonance that follows bindu, the last point that the experiencer holds to before relinquishing all sense of time and space. The transcendent bruit that is nada begins to reverberate through one’s self-awareness as soon as all differentiating thought disappears. Nataraja straddles the bindu fence between creation and destruction, everlastingly awash in the nada tide that He Himself engenders.

Nothing in the universe moves but Nataraja; all else that shifts position, form or condition does so solely through His whirl. Nataraja is the perfect embodiment of a Vedic formula for compressing Reality into words: satyam, rtam, brhat (“the true, the harmonious, the vast”). Reality exists (it displays truth, satyam), it has a natural order or rhythm (rtam) which is self-perpetuating and self-correcting (it is harmonious), and it is all-pervasive, extending beyond the farthest reaches of the human imagination (it is vast, brhat). Nataraja’s form expresses the solidification of resonance, the congealing of music and dance into form. The word ambara can also mean “garment,” and chid-ambaram thus also means “clad in consciousness,” in the same way that a naked sadhu is sometimes spoken of as being dig-ambara, “sky-clad, clothed in the ten directions.” Awareness covers the Lord of Dance, it surrounds Him as it emerges from Him. Alone at the center of the cosmos, He is the embodiment of the consciousness that gave the cosmos birth. Within the human microcosm Nataraja relentlessly dances a tarantella of blood and lymph at the heart-center, thumping out the rhythm of heartbeats endlessly disseminating oxygen and prana, the life force. Like the heart, which sits at the core of the chest, the center of any space or image, in or out of the body, should be relatively empty of matter but full of prana. Any central area is a “heart,” a chid-ambaram that should reflect and express ultimate nature, ultimate sound and rhythm by concentrating prana there. Prana, mind and breath all work together, in the internal and the external universe alike.”

The power (Hara) of the unmanifested absolute (Shiva), when manifested becomes the dynamic cosmic energy (Shakti), much like potential energy transforming into kinetic energy, from inertia to motion. The sound of this energy when “expressed” as Svoboda says, creates matter in various forms and size, ranging from atoms to galaxies to universes.

In the human form, the energy itself, first, manifests into thousands of ethereal energy channels or meridians (72,000) that carry the nada in and out of the body. It is my supposition, that these channels are thus called the naadis.

Inherent, within the nada, are laya and taala, the tempo and the beat. It is no wonder then why human beings are inherently perceptible to music at any age. Rhythmic vibrations, interspersed with silence, pattern within silence and silence within pattern. Space within matter and matter within space, matter that is nothing but energy bound in certain vibrations. We and the whole universe is nothing but these vibrations within and without.
